How many threads CSI2RX have? 32 (as per commit message) or 64? If I recall right, it is 32. > > drivers/dma/ti/k3-psil-j721e.c | 73 ++++++++++++++++++++++++++++++++++ > 1 file changed, 73 insertions(+) > > diff --git a/drivers/dma/ti/k3-psil-j721e.c b/drivers/dma/ti/k3-psil-j721e.c > index 7580870ed746..34e3fc565a37 100644 > --- a/drivers/dma/ti/k3-psil-j721e.c > +++ b/drivers/dma/ti/k3-psil-j721e.c > @@ -58,6 +58,14 @@ > }, \ > } > > +#define PSIL_CSI2RX(x) \ > + { \ > + .thread_id = x, \ > + .ep_config = { \ > + .ep_type = PSIL_EP_NATIVE, \ > + }, \ > + } > + > /* PSI-L source thread IDs, used for RX (DMA_DEV_TO_MEM) */ > static struct psil_ep j721e_src_ep_map[] = { > /* SA2UL */ > @@ -138,6 +146,71 @@ static struct psil_ep j721e_src_ep_map[] = { > PSIL_PDMA_XY_PKT(0x4707), > PSIL_PDMA_XY_PKT(0x4708), > PSIL_PDMA_XY_PKT(0x4709), > + /* CSI2RX */ > + PSIL_CSI2RX(0x4940), > + PSIL_CSI2RX(0x4941), > + PSIL_CSI2RX(0x4942), > + PSIL_CSI2RX(0x4943), > + PSIL_CSI2RX(0x4944), > + PSIL_CSI2RX(0x4945), > + PSIL_CSI2RX(0x4946), > + PSIL_CSI2RX(0x4947), > + PSIL_CSI2RX(0x4948), > + PSIL_CSI2RX(0x4949), > + PSIL_CSI2RX(0x494a), > + PSIL_CSI2RX(0x494b), > + PSIL_CSI2RX(0x494c), > + PSIL_CSI2RX(0x494d), > + PSIL_CSI2RX(0x494e), > + PSIL_CSI2RX(0x494f), > + PSIL_CSI2RX(0x4950), > + PSIL_CSI2RX(0x4951), > + PSIL_CSI2RX(0x4952), > + PSIL_CSI2RX(0x4953), > + PSIL_CSI2RX(0x4954), > + PSIL_CSI2RX(0x4955), > + PSIL_CSI2RX(0x4956), > + PSIL_CSI2RX(0x4957), > + PSIL_CSI2RX(0x4958), > + PSIL_CSI2RX(0x4959), > + PSIL_CSI2RX(0x495a), > + PSIL_CSI2RX(0x495b), > + PSIL_CSI2RX(0x495c), > + PSIL_CSI2RX(0x495d), > + PSIL_CSI2RX(0x495e), > + PSIL_CSI2RX(0x495f), > + PSIL_CSI2RX(0x4960), > + PSIL_CSI2RX(0x4961), > + PSIL_CSI2RX(0x4962), > + PSIL_CSI2RX(0x4963), > + PSIL_CSI2RX(0x4964), > + PSIL_CSI2RX(0x4965), > + PSIL_CSI2RX(0x4966), > + PSIL_CSI2RX(0x4967), > + PSIL_CSI2RX(0x4968), > + PSIL_CSI2RX(0x4969), > + PSIL_CSI2RX(0x496a), > + PSIL_CSI2RX(0x496b), > + PSIL_CSI2RX(0x496c), > + PSIL_CSI2RX(0x496d), > + PSIL_CSI2RX(0x496e), > + PSIL_CSI2RX(0x496f), > + PSIL_CSI2RX(0x4970), > + PSIL_CSI2RX(0x4971), > + PSIL_CSI2RX(0x4972), > + PSIL_CSI2RX(0x4973), > + PSIL_CSI2RX(0x4974), > + PSIL_CSI2RX(0x4975), > + PSIL_CSI2RX(0x4976), > + PSIL_CSI2RX(0x4977), > + PSIL_CSI2RX(0x4978), > + PSIL_CSI2RX(0x4979), > + PSIL_CSI2RX(0x497a), > + PSIL_CSI2RX(0x497b), > + PSIL_CSI2RX(0x497c), > + PSIL_CSI2RX(0x497d), > + PSIL_CSI2RX(0x497e), > + PSIL_CSI2RX(0x497f), > /* CPSW9 */ > PSIL_ETHERNET(0x4a00), > /* CPSW0 */ > -- Péter

If I > recall right, it is 32. Ah, sorry I forgot to update the commit message. Each instance of CSI2RX has 32 threads, and J721E has 2 instances. So 64 threads total.

The CSI2RX subsystem uses PSI-L DMA to transfer frames to memory. It can have up to 32 threads but the current driver only supports using one. So add an entry for that one thread.
